| 摘要: |
| 以中间侧送风，下回风的流场作为实验研究模型，研究两台空调制冷机在不同的摆放位置，以不同的送风速度及不同送风角度运行，对室内气流、温度场和温度下降速率的影响。实验结果表明：两空调机的相对位置对空调房温度下降速率影响最大，其次是送风角度（导风板角度）和送风速度；当两空调机置于房间长边两端，导风板位于90度角时（即冷风水平方向送出），这种组合使室内温度下降较快；当两空调机于房间对角放置，室内温度下降总是最慢；导风板位于120度角（冷风斜向上送出），其温度场的温差较小。对其机理进行了初步探讨。 |

| Abstract: |
| The experiments were conducted to determine the influences of some factors on the air flow fields and temperature distributions in an air-conditioned room.The results show that the positioning of the air-conditioners influences the cooling rate dominantly and the air discharging angle and speed also have certain effect.In particular,the average indoor temperature decreases faster when the two air conditioners are at opposite ends of the room long side and the air discharges in the horizontal direction.Moreover,the air temperature drops more slowly when the two air conditioners stand corner to corner in the cross.In addition,the temperature field has the minimum temperature difference when cool air issues at an angle of 120 degrees. |
